Weather Wise

Measuring the Weather

Developing Skills of Inquiry, Design and Communication
- design, construct, and test a variety of weather instruments
- use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations


The following web site describes some of the instruments meteorologists use to collect data about the weather.

Use the information to complete the chart.
The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.

Clouds

Understanding Basic Concepts
- explain the formation of clouds and the effects of different cloud formations on weather and climate


Use this web site to answer the following questions.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/clouds.html

1. What are clouds? Clouds are water and ice particals flouting in the air.
2. Explain how clouds form. Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets.
3. What are the 3 "families" of clouds and what do their Latin names mean? Cirrus means 'curl of hair', cumulus means 'heap', and stratus means 'layer'.
4. Follow the links to learn about each type of cloud and then complete the table on the next page.
To help you identify clouds, download, print and construct the following "Cloud Key".

Forecasting

Understanding Basic Concepts
-recognize large-scale and local weather systems
- predict local weather patterns using data from their own observations of weather and from weather reports
- identify patterns in air movement


Read the details at http://weathereye.kgan.com/cadet/forecast/camp.html and follow the links.
The following questions and organizers will help you keep track of the crucial information you’ll need.
